    no sound in kubuntu 12.04

    i am running kubuntu 12.04 (precise) for the first time.

    previously, i was running 10.04 (lucid). i backed up, wiped the disk, and installed a clean operating system.

    (in spite of the fact that i've been running kubuntu since dapper drake, i still don't know anywhere near as much about linux, as i do about windoesn't or macintosh machines, which is why i posted this in the "Help The New Guy" forum. i hope it's okay.)

    when i was running lucid, the sound worked, sort of: the music player (amarok) worked fine, but when i played videos from youtube, the video would work, but the sound did not. this was not a major issue, but it is the primary reason i wanted to install a clean system, rather than upgrading.

    unfortunately, it worked the opposite way: when i booted up precise, there was no sound at all. not in amarok, or anything else.

    of course, the first thing i did was check the multimedia settings, which showed that i have TWO audio playback devices installed.

    i have no separate sound card: the audio is on the motherboard, which has an AMD i386 processor. however, the multimedia settings have an "RS780 HDMI Audio [Raedon HD 3000-3300 Series] Digital Stereo [HDMI]" as well as a "Built-in Audio Analog Stereo" device installed...

    NEITHER of them work... AT ALL...

    i've messed around with it a little bit, but i honestly have no clue what i'm doing, so i may have messed it up even more, without realising it.

    i've got most of my computer back up and running the way i want it to, but the lack of sound is really getting me down.

    any suggestions?

      the "Headphone" and the "Front Mic" are turned all the way down, but that shouldn't affect the speakers, which come out of the back of my computer...

            I'm going to have you install phonon-backend-gstreamer

            Open a console and type:
            Code:
            sudo apt-get install phonon-backend-gstreamer
            When it has finished, open System Settings > Multimedia > Phonon > Audio Hardware Setup and change:

            Sound Card to Built-in Audio
            Profile to Analog Stereo Duplex
            Sound Device to Playback (Built-in Audio Analog Stereo)
            Connector to Speakers

            Then click on the Backend tab and select GStreamer and move it to the top. Click Apply and then close. Log out and reboot.

              the only "Connector" i have offered is "Analog Output"

              it still doesn't work, but it makes a few more noises than it used to -- the "beep" when it reboots is new, and it sounds like the speakers are being "turned on" shortly afterwards, but no sound comes out.

              also, in System Settings > Multimedia > Phonon > Audio Hardware Setup i changed everything, as you said, but when i reboot, it changes back to RS780 HDMI Audio... that's not right... 8/

                You have VLC installed. Let's 'simulate' what would be removed if it's uninstalled/purged. Open a console and type:
                Code:
                sudo apt-get purge --simulate vlc
                Copy the output (unless it just reports that vlc* will be removed) and paste it in your reply.

                        I'm going to suggest that you uninstall/purge vlc (it can always be reinstalled). Let's see what will actually be removed/purged with a simulation:
                        Code:
                        sudo apt-get purge --simulate libvlc5 libvlccore5 phonon-backend-vlc vlc vlc-data vlc-nox vlc-plugin-notify vlc-plugin-pulse
                        Copy/paste the output.

                            Okay, so nothing other than the specified packages. Go ahead and actually purge them. Just repeat the command but omit the --simulate option. Then log out and reboot and go back into System Settings > Multimedia and check the settings.

                              ooh, that's weird...

                              now i have three devices listed in System Settings > Multimedia > Phonon > Audio Playback Default Audio Playback Device Preference:

                              RS780 HDMI Audio [Radeon HD 3000-3300 Series] Digital Stereo (HDMI)
                              Built-in Audio Analog Stereo
                              Built-in Audio Digital Stereo (IEC958)

                              of those, the first two look like they might actually do something. the last option (Built-in Audio Digital Stereo (IEC958)) is "greyed out"...
